Need helps draining the transmission fluid.
 

I recently just broke in my car. Should I drain both the engine and transmission oil? And what brand do you guys recommend? I also want to learn doing it myself any helpful video would be great :)

No need to change the oil and transmission fluid. Just follow the regular maintenance schedule for those. The engineers that designed the car knew what they were doing when they set the schedule.

CONGRATULATIONS on getting your car broke in ....... now, the fun begins.....:burnrubber:

About the engine and transmission oil ........ like @Tcoat said, I suggest you just follow the maintenance schedule in your manual.

Some feel it's better to change the crankcase and MT oil sooner because of a buildup of metal shavings. Personally, I think that's a concern of the past.

Do they still give the first three oil changes free at the dealer? If so, I'd suggest you take advantage of that program.

This will give you lots of time to :search: and find out how to change the oils.

Thanks for the help I was just reading in another thread about changing your transmission fluid early because of metal shards or something like that and yeah the dealership I went gives you 6 free oil change :thanks:

Is it an automatic or manual?

Manual transmission

swap the fluid for Motul Gear 300

Personally, I would swap the transmission and rear end oil with Motul 300 ASAP.


At 10,000 miles mine had a ton of metal shavings on the diff plug. Transmission fluid looked good but it definitely feels better when shifting and not as clunky when cold. It is worth it for piece of mind....the first fluid change on the diff in these cars is usually pretty gross. The magnetic plug always has shavings.

Diff

Yep, there are two schools of thought about when to change the MT and differential oils.

The new school (made up of the old codgers like @Tcoat and myself) who believe that the beginning oils are good for a while. Then there is the old school (made up of usually new folks) that feel the oils should be changed after a few thousand miles.

Now, go figure that old - new bit ....... :iono:

Now, I understand that ol @Tcoat has had the OEM transmission oil in place for 40,000 + miles. Maybe when he goes to drain it out, it won't come out and he will have to flush it out with hot kerosene OR remove the transmission, crack the case and scrape it out with a putty knife ...... :eyebulge:

I think i might try it this weekend, how many liter do i need for the transmission and the diff, would one bottle of Motul gear 300 cover it. And last question how often should this be replaced?

Search for and download the repair/service manual. It lists all the how to and info you need.

search, but no.

You need 4L of fluid(only use about 3.5ish of it though).

18k I think is when they say to swap it...but it wont hurt doing it more often either.

Frankly, with the way the diff looks after 18k, I'd do it sooner IMO.

A little over 2000 miles here on a manual 2016 BRZ. I changed my fluids last weekend. The transmission fluid was clear but had a metallic sheen. The differential fluid was black and the drain plug was coated in metal shavings. I think these cars benefit from doing an early fluid change once everything breaks in. I was surprised at how much junk was in the differential. Mine looked similar to the one posted above but with only 2000 miles on it.

I also recommend Motul if you can get it. After doing some extensive reading, it seems like most people have the best luck with Motul in the differential and transmission.

I have also read good things about Pennzoil Synchromesh for the transmission. This is what I used. It shifts perfectly now. I noticed a little clunkyness going into 2nd, as so many others have reported. After changing the fluid, it shifts much smoother. For the rear differential I used Mobil1 75w-90 gear oil. Like I said, I didn't have access to Motul and for me, Mobil was a close second.

I screwed up out of sheer laziness. I took my car into Valvoline to change the oil. My shifter was clunky as hell so I asked them to flush the transmission fluid and replace it with their top brand. It worked very well for a month but now 1st and 2nd gear are even worse than they were before. Should I just grab some Motul Gear 300 and do it myself?

I did both my transmission and differential with Motul 300 at approximately 5k miles and have had no complaints, I basically did it for the learning experience, peace of mind, and the "I-want-to-do-something-nice-to-my-car-today" feeling.

If you can do an oil change you can do it. You just need the 10mm hex/Allen wrench.

Thanks. I've thought about taking the car back since I have a warranty for the service, but I cannot imagine anything they could do to improve the situation (besides just give me my money back.)

These transmissions are made for GL-3 gear oil. GL-4 will also work but you can not use GL-5 oil which is what the majority of gear oils are. GL-3 and 4 oils are sulphur free. The transmission has brass and copper components and sulphur can degrade these parts. GL-5 contains sulphur and should not be used. If they used a GL-5 oil then you need to have it replaced. I would recommend either Subaru OEM gear lube, Pennzoil Synchromesh or Motul 300 which are all safe for yellow metals.

Engine oil should be fine as long as it's synthetic. The owner's manual states that these engines require synthetic oil. 0W-20 Mobil is what I used.

Thankfully I kept the invoice and looked up the trans fluid used. Looks like they used a GL-4 MT fluid and 0W-20 synthetic for the engine.

I'll have to keep looking to why it's so hard to shift into 1st and 2nd after driving 10-30 meters. Thanks for the oil suggestions.

Mine was a little difficult to shift into second as well. I've found that these transmissions like to be shifted at higher RPMs than I was used to. Try revving a little higher in first before shifting into second. Also, they like to be warm. I've found that after driving for a few miles, the transmission warms up and the shifts get a lot smoother.

Here is one of the most useful posts I've found here: http://www.ft86club.com/forums/showp...0&postcount=82

I followed the advice and let the engine rev a little higher (run lower gears) while the engine is warming up. This increases friction to the oil which heats it up faster. I've found that my transmission shifts smoother much faster if I don't bog the engine down when it's cold, but let rev a little. I drive smoothly but one gear lower than I would normally use. This gets the transmission shifting great in no time.

I didn't read the whole thread, just this first post. I would recommend doing transmission and differential. I bought my car at 12000 miles, and changed fluids a few thousand after that. Both my transmission and differential were very dark and had a lot of sediment, my drain plugs were caked in metal shavings. That's why I recommend it, just in case. Only costs maybe 40$ in fluids. Well worth the piece of mind IMO. I use Amsoil products. Visit a store ir call them and they will tell you what you need. All the big names are fine, I'd just avoid the cheap Wal-Mart stuff and the overpriced Japanese stuff(quality is fine just over priced unless you are a dedicated track guy)
